ABSTRACT:
The system includes a side-folding, extendable frame comprising a plurality of generally U-shaped tubular frame members arranged on their sides so that the base of the "U" alternately forms rear and front legs for the frame. The ends of adjacent frame members are connected for rotation about horizontal axes by couplers which limit rotation of the frame members so that the frame has a zig-zag shape in the use position with all rear legs inclined toward one side of the frame and all front legs inclined uniformly toward the other side of the frame. Seats extend between and are supported by the frame members. Although various types of seating may be used, in a preferred embodiment, each seat is hinged at its side to an associated frame member, so that in the storage position, the frame members and seats are folded vertically to side-by-side relation, and the seats nest within each other for minimum space. A dolly may be used to fold the seating, and transport it to and from storage.
